SYNOPSIS
</b><br>
<P>
<b>#include &#60;pcre2.h&#62;</b>
</P>
<P>
<b>int pcre2_jit_compile(pcre2_code *<i>code</i>, uint32_t <i>options</i>);</b>
</P>
<br><b>
DESCRIPTION
</b><br>
<P>
This function requests JIT compilation, which, if the just-in-time compiler is
available, further processes a compiled pattern into machine code that executes
much faster than the <b>pcre2_match()</b> interpretive matching function. Full
details are given in the
<a href="pcre2jit.html"><b>pcre2jit</b></a>
documentation.
</P>
<P>
The first argument is a pointer that was returned by a successful call to
<b>pcre2_compile()</b>, and the second must contain one or more of the following
bits:
<pre>
  PCRE2_JIT_COMPLETE      compile code for full matching
  PCRE2_JIT_PARTIAL_SOFT  compile code for soft partial matching
  PCRE2_JIT_PARTIAL_HARD  compile code for hard partial matching
</pre>
There is also an obsolete option called PCRE2_JIT_INVALID_UTF, which has been
superseded by the <b>pcre2_compile()</b> option PCRE2_MATCH_INVALID_UTF. The old
option is deprecated and may be removed in the future.
</P>
<P>
The yield of the function is 0 for success, or a negative error code otherwise.
In particular, PCRE2_ERROR_JIT_BADOPTION is returned if JIT is not supported or
if an unknown bit is set in <i>options</i>. The function can also return
PCRE2_ERROR_NOMEMORY if JIT is unable to allocate executable memory for the
compiler, even if it was because of a system security restriction.
